Airtac TCM Triple Axis Cylinder TCM32X70-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM32X70-S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 70mm stroke on twin guide rods. Its integrated brass sliding bearing gives high radial-load and impact resistance — about double the horizontal impact tolerance of a plain cylinder, holding the tool square to ±0.06° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM32X70-S
The AirTAC TCM32X70-S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It produces 402 N of push thrust at 0.5 MPa (563 N at 0.7 MPa) and utilizes a Ø16 mm piston rod. The integrated twin guide rods deliver a non-rotating accuracy of ±0.06°, keeping a gripper or blade perfectly square under heavy off-centre loads without needing an external linear rail.
Designed for punishing environments, the brass sliding bearing shrugs off dust, grit, and hard knocks, offering about double the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam. You can plumb the 1/8" PT ports from either the upper face or side, and the standard built-in magnet works seamlessly with CS1 reed or DS1 electronic switches across four sensor slots. Stroke termination relies on fixed TPU rubber bumpers, meaning there is no adjustable air cushion screw to set.

Specifications follow the official AirTAC TCL/TCM series datasheet (JIS standard). Confirm against the product label before installation. Thread options: PT (blank) / G / NPT. Every TC model ships with a built-in magnet for sensor switches.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max | 82 kgf | |
Force is set by the bore and piston rod (Ø16 mm); the twin guide rods carry side load and torque, not thrust. Actual usable force is lower than theoretical due to friction and back-pressure.

Where the Airtac TCM Triple Axis Cylinder TCM32X70-S Is Used
Pallet Transfer Line Stop
Halting heavy moving pallets on a dusty transfer line is easy for the 402 N push at 0.5 MPa. The brass sliding bearing tolerates abrasive grit and repeated hard side-impacts where a steel-ball guide would wear prematurely.
Foundry Sand Mould Press
Compressing sand moulds in a dirty foundry demands high torsional rigidity. The ±0.06° non-rotating tolerance keeps the press plate perfectly level under an uneven load, while the brass sleeve handles airborne sand and heat.
Off-Centre Gripper Slide
Moving a heavy gripper that grips parts off-centre generates high torque. The twin guide rods absorb this moment load directly, delivering 563 N of thrust at 0.7 MPa without needing a separate external slide rail.
Is the Airtac TCM Triple Axis Cylinder TCM32X70-S the Right Cylinder?
If 402 N of push at 0.5 MPa is too much for your layout, step down to the Ø25 bore which yields roughly 245 N, or move up to the Ø40 bore providing 628 N for heavier gates. Choose the sister TCL series with its steel-ball linear bearing only if your application demands low friction and high precision for vertical high-load work. To replicate this exact unit, specify a 32 mm bore, 70 mm stroke, 1/8" PT ports, and the standard S magnet.
Because this is a double-acting cylinder, it will drift downward if air pressure drops or the valve is centred; the guide resists rotation, not gravity. For fail-safe load holding, install an external rod lock or a pilot-operated check valve. The 70 mm stroke falls well within the 250 mm maximum standard limit for this bore.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Side load / torque the guide must carry
- ✓ TCL (precision, low friction) vs TCM (impact, radial load)
- ✓ Stroke & mounting face (top / bottom / rear)
- ✓ Port/thread type (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check The guide unit takes side load & torque — but do not exceed the max safe load/torque for your stroke.
- check Mount from the top, bottom (screw or T-slot) or rear face; use the precision locating holes.
- check Do not disassemble the fixing block or guide unit — factory-set precision.
- check Fit CS1 / DS1 magnetic switches in the four sensor slots as needed.
Airtac TCM Triple Axis Cylinder TCM32X70-S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push and 302 N of pull. At its maximum 0.7 MPa operating pressure, the push increases to 563 N. The theoretical maximum force is 82 kgf. The operating pressure range is 0.15-1.0 MPa.
Each end of the cylinder uses a fixed rubber TPU bumper to soften the impact; there is no adjustable air cushion screw. For position sensing, the standard built-in S magnet interfaces with AirTAC CS1 reed or DS1 electronic switches, which drop into any of the four sensor slots on the body.
